Investigation and Fuzzy Comprehensive Evaluation on Pollution Status of Heavy Metal of Pu River

This paper mainly monitors and evaluates the sediment quality of Pu River which flows through Shenbei new district in Shenyang city,in terms of indicators of the water quality of Pu River,including pH,organic matter content,heavy metals(Cu,Zn,Pb,Cr,Cd),etc.in sediment.Contents of heavy metals were measured by OPTMA 3000.The sediment quality of Pu river was evaluated by using fuzzy comprehensive evaluation.It was found that the organic matter content in sediment is relatively low,sediment in Pu River was seriously polluted,especially Cr pollution is significant,and sediment of Pu River is polluted by the combined pollution of Cr,Pb,Zn and Cu.
